<p><P>PROBLEM TO BE SOLVED: To provide a small-size and lightweight oxygen concentrator producing little noise in the pressure swing adsorption oxygen concentrator. <P>SOLUTION: This pressure swing adsorption oxygen concentrator is provided with an adsorbent bed 2 preferentially adsorbing nitrogen rather than oxygen, and an air supply means 6 supplying a material air to the absorbent bed. This concentrator is further provided with an airtight vessel 5 having the air supply means 6 in its inside and having airtightness under an atmospheric pressure or less, and a decompressing means for the airtight vessel by an airtight vessel decompressing pipe 10. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
